Current Stock:

This cassette from the Ultegra series provides smooth, lightning-quick shifting. The tolerances have been increased compared to previous models for even better performance.

  • Aluminum sprocket carrier and alloy lock ring keep the cogs in check when shifting under load.
  • Sprockets have a nickel-plated finish.
  • Compatible with super narrow HG 10-speed chains.

    Shimano parts perform as expected. I added this to my wahoo kickr core with the spacer and is exactly what I needed.
